Palin and Robertson first bonded during an NRA convention over the summer. Most recently, the two spent time together when Palin's "Good Tidings and Great Joy: Protecting the Heart of Christmas" book tour stopped at the Robertson's hometown in Louisiana earlier this month.

Palin has even commended Phil Robertson's open view against abortion.

"Phil Robertson offered some of their refreshing trademark plainspoken talk that so many crave from our leaders in Washington," Palin wrote in a Facebook photo caption on Aug. 21. "Speaking on the issue of the sanctity of life, Phil reminds us that all life is God-given, no matter how small or how special."

Palin also argued that Washington, D.C., should be more like the "Duck Dynasty" family.

"To our GOP leaders in Washington, especially—this is what Americans desire and deserve; we're not rooting for your social truces. As Phil so rightly asks, 'What in the world has happened to us? Kudos to these Duck dudes for speaking their minds, and for their boldness in living the American dream of LIFE, liberty, and the pursuit of happiness—reminding us all that it's only with freedom that anything is possible."
